Part: 1

Explain Fourier zoom

1. Image M is Fourier transformed cfft(M) ... 2. Splitted/pitched in the 4 Cartesian corners by inserting 'nc' n_cols of 0's and 'nr' n_rows of 0's. 3. The cross-padded creation is Fourier inversed Re[icfft], thus recovering the zoomed image over 'nc' & 'nr' supplementary cols/rows vs the original M image. 4. Fourier zoom Pad(M,nc,nr) is of extraordinary quality and realism up to zoom factor 2. 5. Each direction [vertical/horizontal] is finally adjustable in increments of one pixel or at will.

1. Plug the original image in your file. 2. READRGB 3. Explode R,G,B 4. Zoom Fourier. 5. Export the zoomed components r,g,b

1. Fourier zoom pad is applied to each RGB component 2. The zoomed image is vectorised with a typical zoom light factor

Zoom the components

In the process of filling the black holes created in 'S', pixels are weighted from the Fourier inverse mwifft2(S),thus affects the "luminosity" of the zoomed RGB. This can be compensated via a luminosity intensifier.

Part: 2

... next Part: 2, addresses vectorizing the [r, g, b] components over a function to increase the luminosity. Part: 2 computes in ~ 12 min.
